How to do a good job in diesel generator room sound engineering

We all know that the design of the diesel generator room is very important,because will directly affect the service life of the diesel generator set and fault occurrences.
Sound insulation:1.into the wind system in the plane into the wind set sound attenuation trough and sound barriers,the forced ventilation ways the fresh air needed for the normal operation of the unit.
2.the sound insulation of the exhaust system.Set the sound attention trough and sound barriers on surface of the exhaust air,forced ventilation,reduce the generator working environment temperature to the largest extent.
3.computer room in and out of the channel noise:in line with convenient transfer into,v and principles of computer room personal work convenient to set up one or two sound insulation door metal framework,with high quality sound insulation materials,thickness of 8 cm to 12 cm as appropriate.
4.sound-absorbing wall and sound-absorbing ceiling,chuck box installed in the computer room sound material,in order to prevent the noise coming from machine room roof and spring back,reduce the room noise decibels.
Sound system:5.flue pipe outside room is installed on the secondary damping type sound to cry,to reduce the engine exhaust noise,and don't affect emissions at the same time.
